What digital makes up for in reciprocity failure it more than

The real state of the art for pinholes is twofold:

1) Laser drilling
or
2) spark erosion drilling

Both make nice pinholes down to about 0.001 inch. Lasers go smaller.

One can buy such pinholes at reasonable prices (i.e. a few to a few tens
of dollars).


Accuracy is not that important. It just helps estimate the first
exposure times. Once a few tests are done, the actual aperture can be
calculated. Nearly round is round enough.

I don't feel like shooting film for such, but I might use a lens adaptor
and shoot some digital pinholes... the very long exposures may be quite
noise prone, however...




Just noticed this item after reading the exposure problem.

You can use a body cap and make a pinhole through that, if that is too
close then use an extension tube. Drill a hole through the cap and
stick some aluminium tape and make a pin prick through it. I usually use
a thick sewing (darning) needle.


I have an adaptor for Hassy lenses for my A-mount (Sony). So I can
"adapt" all manner of extensions to that. Making the aperture itself
(alu paper/pin) is the least trouble. I have a micrometer to measure
the aperture of the pin or needle and the film plane is well marked to
get the FL. I'll probably go for a wide-ish FOV - the adaptor alone
will probably be enough.


I am looking forward to seeing the results.
please share them.

Don't hold your breath. I haven't done any photography in Jan. Trend
is not looking better.

What digital makes up for in reciprocity failure it more than
compensates for in noise...


Whereas good old chemical film is grain free and can be
averaged over multiple exposures easily?

Obviously, you have never shot film.

Although I do not like to ust cite Wikepedia, there is sufficient
information to show how wrong you are.

I have a feeling you are responding to Wolfgang's demonstration of
Teutonic sarcasm.

Don't feel bad, it was very subtle, sort of like the bombardment
and the subsequent landing in Normandy.
The Führer *knew* the real landing would happen in Calais.
